CaymanS engine cover fits right on. It's raised in the middle. You have to transfer the 986 DZUS fasteners and add a washer to them. The 987 engine cover is alum and much thinner/lighter
Every car I crawl underneath with a lowered 3.4 has beat up headers... every one of them.
Want to make more power? Install the CaymanS air box in the 986. It requires removal of the *muffler* chamber and slight movement of the vent line from the gas tank
I'm tired of seeing all the "hot air" intakes other shops have used in the past.
